Although the teen drama couldn't get any more serious with all of the turmoil and heartbreak onscreen, the cast looked genuinely happy together offscreen. The BTS photos show Lee Min Ho always being a good sport as the hyung of the cast, Park Shin Hye showing her aegyo as if she wasn't cute already, Kim Woo Bin being his charismatic self with some bromance going on between him and Hyungsik as a bonus, and Krystal and Minhyuk making fans wish they would just date in real life with their perfect chemistry.

A rep commented, "Lee Min Ho, Park Shin Hye, Kim Woo Bin, and the other top actors of 'Heirs' as well as the staff poured out all of their passion, making a high-quality drama."

Stay tuned for the finale of 'Heirs' this week!
